In order to become a target, it is provided on the left side in front of the cooking chamber 8 which is a position facing the first temperature viewing means.

  Then, the first temperature detection means 21 and the second temperature detection means 22 detect the left and right temperatures in the cooking chamber 8 every few seconds and send them to the control means (not shown). And the entire cooking time is determined from the time when the two average temperatures reach the set temperature.

  Next, grilled food cooking in the above embodiment will be described with reference to FIGS.

  First, a grill net 14 is placed on the saucer 11, and a cooked product 15 such as fish is placed thereon and inserted into the cooking cabinet 8 as shown in FIG.

  Next, when the operation unit 5 is operated to start automatic cooking, as shown in the cooking procedure of FIG. 4, first, the catalyst heater 20 is energized, and the catalyst 16 for air purification is heated by the catalyst heater 20.

  In this state, when a time t1 (about 30 seconds) until the energization of the lower heating element 10 is stabilized and a time t2 (about 60 seconds) until the air purification catalyst 16 is preheated by the catalyst heater 20 elapses. The temperature inside the cooking chamber 8 is stabilized, and the average detected temperature T (normally substantially coincident with the room temperature) of the temperature detecting means 21 and 22 at this time is stored in the microcomputer of the control means as the average initial temperature T0.

If the detected temperature T is abnormally high (for example, 80 ° C. or higher) even after t2 hours have elapsed, such as when grilling fish or the like continuously, the average detected temperature T is decreased to a predetermined temperature of 80 ° C. or lower. The upper heating element 9 and the lower heating element 10 are not energized, and the exhaust fan 18 is energized, and the average detected temperature T when the temperature is lower than the predetermined temperature 80 ° C. is set as the initial temperature T0 to the microcomputer of the control means. Remember.

  Further, when there is no air purification catalyst 16, catalyst heater 20, exhaust fan 18, etc., the operation is performed while omitting a predetermined time t2 (about 60 seconds).

  In FIG. 4, after time t2 has elapsed from the start of cooking, the exhaust fan 18 is energized, and the exhaust fan 18 exhausts the air in the cooking cabinet 8, and at the same time, the lower heating element 10 is energized to generate heat and cooking. The object 15 is heated. Also at this time, the temperature of the first temperature detecting means 21 and the average temperature value of the second temperature detecting means 22 are calculated every several seconds (about 1 second). As a result, the temperature in the cooking chamber 8 rises, and the average temperature reaches the determination temperature T1 as shown in FIG. The elapsed time at this time is defined as a detection time t0. The determination temperature T1 is determined by the following determination temperature calculation formula with correction by the initial temperature T0. Each constant is different for each automatic menu.

(Example 1)
Automatic menu round T1 = A1 + T0 × B1
Automatic menu tsukeyaki T1 = A2 + T0 × B2
A1, B1, A2, B2: Constants When the determination temperature T1 is reached, the remaining time t is determined by the following remaining time calculation formula corrected by the detection time t0. Each constant is different for each type of automatic menu.

(Example 2)
Automatic menu roast t = C1 + t0 × D1
Automatic menu tsukeyaki t = C2 + t0 × D2
C1, D1, C2, D2: Constants The remaining time t determined by the above calculation is displayed on a display unit (not shown) provided on the upper front portion of the main body 1, and thereafter, the upper heating element 9 and the lower heating element 10 The cooked food 15 is heated while energizing alternately, and the remaining time displayed on the display unit is subtracted with the passage of time.

During this time, smoke generated from the cooked product 15 such as fish is deodorized and deodorized while passing through the air purification catalyst 16 from the exhaust outlet 8a provided at the rear upper part of the cooking chamber 8, and through the exhaust passage 17, the upper surface of the rear part of the main body 1 It is discharged from the opening 1a to the outside (indoor).

  Thereafter, when the time t has elapsed and the remaining time display becomes 0, the energization of the lower heating element 10 is stopped and the buzzer is sounded to notify the user of the end of cooking.

In the cooking process, the first and second temperature detection means 21 and 22 are installed substantially symmetrically, and the average temperature of each temperature detection means 21 and 22 is calculated as shown in FIG. When the cooked food 15 is placed in the cooking cabinet 8 in a biased manner, the temperature is appropriately determined regardless of where the cooked food 15 is placed on the grill 14, and the same baking is obtained each time.

  Moreover, when the quantity of the foodstuff 15 differs, for example, when there is much quantity of fish, the temperature rise of the cooking chamber 8 takes time, so that the quantity is large. FIG. 6 shows an example of one fish and five fish as an example of a small amount of food and an example of a large amount.

  Even in this case, the average temperature detected by the first and second temperature detecting means 21 and 22 is calculated as shown in FIG. As a result, in the case of five samas, the detection time t0 to reach the determination temperature T1 is longer than in the case of one, so the remaining time t is also increased in proportion to t0 from the remaining time calculation formula. For this reason, when the amount of fish is small, the cooking time is short, and when the amount of fish is large, the cooking time is automatically adjusted so as to be long, and the same baking is obtained.

  As described above, according to the present invention, the first and second temperature detecting means 21 and 22 are installed symmetrically in the cooking cabinet 8, and the average temperature of each temperature detecting means 21 and 22 is set every few seconds. Regardless of the size of the cooking chamber 8 and the type and quantity of fish etc., the temperature can be determined appropriately regardless of the location of the grille 14 by the method of calculation, and baked in the same manner every time. it can.
